Testing Clay in a BBQ! Wondering How To Fire Clay Without A Kiln? TKOR Details EVERYTHING! 

“Clay... I’m sorry but I’m gonna have to let ya go” There. Clay is now fired😆

should have FULLY allowed clay articles to AIR DRY! slow moisture purge and evaporation. THEN fired. the remaining moisture in the clay caused your crackings!

Just a quick tip. Like you said, the only ones that broke were the coil pots. Thats probably because they weren't held together well. If you're doing coil, you have to use something called slip which is usually just clay mixed in water. It should be like a paste. You would use that as a glue to keep pieces together. More importantly, you made them as one coil. When doing coil, it should be done one coil at a time not just a long coil. That long coil prevents you from being able to score and slip then together. Scoring means putting marks in the clay so that the slip binds them together better. If you try that, it should prevent extreme cracks like yours was. Much love, someone who just finished his first semester in which he took a ceramics class. Hope that helped.

You're supposed to knead clay while wedging it. Throw it down then push forward and roll it up then repeat. Also slip and score the coils or they won't hold together and don't forget to pinch the coils together to bind them together.

*Art student screaming* You didn't Slip, Score, Seal!

It may have cooled too quickly, clay and glass firing equipment usually has fire-brick surrounding the firing area to insulate it, and let it cool way more slowly than the bbq cools... a bbq will be cool to the touch in a matter of an hour after the fire dies, where the fire-brick ovens that fire glass and ceramics will stay warm for much longer than that...

As someone who does ceramics and goes on the wheel a lot, your “wedging” drove me crazy

NO DONT FIRE ME I CAN HELP THE COMPANY!

You need to score it and use slip also try need in it differently

Dude do some experiments with a laser

You should ask some tips for *Primitive Technology*

Neighbors: Hey, watcha grilling over there? King of Random: ...Clay...

Mix negative x with thermite then add water

Please can you make a backyard kiln?

Wheel Potter - Thoughts on clay cracks - All clay has a percentage of shrinkage when it dries and when it fires. this can be anywhere between 4% to 15% shrinkage. Depending on the size of a piece this can be very minimal (1/4") to over an inch worth of a difference. A piece that has thinner spots vs thicker spots will dry at different rates and change how the piece shrinks uniformly. If a part of the pot shrinks faster than another part, it will separate causing a crack. The Clay needs to dry slowly until it is ready to fire to help prevent cracking. Porcelain is a very fine clay with no grog, it is quite strong when fired, but it also shrinks the most because as it dries the clay particles pack together tighter. The more grog that is included the less shrinkage you will have. Primitive technology was able to quickly dry his pieces by a fire due to the large amount of grog and impurities in his clay that prevented the clay from shrinking so much. A method that I use to help dry slower is to place a bucket, or other solid container, upside down over the piece, on top of stilts to allow a small slit of airflow from the bottom. I've used popsicle sticks, or even 1" thick blocks to raise the upside down bucket a bit. This creates a sort of "damp box" that prevents the moisture from escaping too quickly. Depending on the gap in your bucket, you can extend the drying time up to a few weeks.

As a Potter I found it entertaining to watch this! I'd be curious to see an attempt at a proper pit fire and possible glazing!

What happens if you put clay in a vacuum chamber?

The clay is on fire 🔥

As a ceramics student I was going: AAAAAAAHHHHHHHHH! The entire time.

Loving the regular uploads, Nat is doing an excellent job too!

You guys should do glass blowing in the foundry

That clay has a wife and children! You can't fire him, he needs this job!

Two things I notice. One was your wedging technique. You're supposed to toss it through a stretched wire or fishing line onto a table then knead to further work out any bubbles. The other was using plain water to get the coils to stick together. I was taught that you had to use a thin paste of clay and water known as "slip" to act as a glue for hand built pots. I hope this helps in future projects.

This video crushed my soul on so many levels. Internally yelling at how wrong some of these methods are

You da Man Nate! Love the positive attitude! Keep up the good work!

Can you put bubble wrap in vacuume

Your supposed to score and slip it

The Kings of Random another awesome video idea would be if you made a clay turn table for making pottery!!!

Nate, you're doing a great job. you're pleasant and easy to listen to, and your enthusiasm is evident. I would like to see more of Grant again, maybe more vids with the two of you together.

COOL!!-Make a brick wall

Thanks for the nice information.. I also want to know, whether you have glazed your bowls before heating? And second, can we heat our pots on gas also... Like putting in a slightly big aluminium rice type container on slow heat..?

Thanks me and my little sister are learning to make and use clay in school and that will help a whole lot

Make the clay and put it in liquid nitrogen, what will happen?

you should make a bow and cast some metal arrowheads! :)

I'm so glad you know clay terms

Another awesome video, thanks. You should try using your foundry from earlier videos for firing clay of modifying it. It would be cool if you could build a low cost kiln...

Could you "wedge" clay in the vacuum tub?

Build a remote-controlled clay squishing device, put it in a vacuum chamber with a lump of clay, then squish the clay while under vacuum.

Well done a beautiful work 👍, and the most beautiful addition of translation,

THAT WAS LIT!!!!!!!🔥🔥🔥🔥🔥🔥

Can you use the solar scorcher on clay to see if it will turn to pottery?

When I as in my ceramics class, my teacher always had us loosely place a plastic bag over our works to either keep them moist and workable for the next day, or to let them dry slowly. If you just leave them out in the open right after working them (probably like what you did), then they dry out and shrink too quickly and that's why they crack. When people say to let ceramics dry slowly, they mean REAL slow, like 2-4 days of slowly letting it dry out.

ohhh please do more ceramics! I would love to see if you could build a real in ground kiln in the backyard! also i would love to see more "survival prepper" type videos!

I absolutely love this guy

I wonder if primitive technologys is watching this and is like “lol”

You didn’t slip and score

I am actually in the middle of experimenting with clay. I was surprised to see this at the same time!

That BBQ is 🔥!

Can you fire clay with the Solar Scorcher?

Make a brick wall

hey Kings random I think you should revisit this this project with a homemade clay wheel to throw the clay I feel like you'll have better results.

Clay is just amazing

Can you make paper from a tree?

If you put food coloring in water and then put it in the distiller you used in a previous video and would the food coloring evaporate with it and land in the top or would it stay behind

Dang ... You made a bowl ... Will wonders never cease ...

How would the homemade charcoal do in this? Was there a ratio of how much wood charcoal to use for how much of the charcoal here?

Clay: “First you throw me on the table, then you fire me... 😢😢😢 WHY??? What have a done???”

I made a play button with my clay.

The duke of random has arrived and is here to stay

Living in a place that is pretty much always summer is probably great for doing experiments

Do it again please

Can you make a silicone mold for the link sword from a previous video and cast some polyeurethane swords as gifts or maybe cast chocolate into it

I just watched that old Clay video yesterday and asked if you could make and fire casting molds! Lol

I feel like I’m in my ceramics class again just by watching this video

You should try to melt down plastic and cast it into a mold

Contact Primitive Technology

You have the best videos!!!!!!!!! You are so cool!!!!!!!!!!!!!

I'm in intro to 3D art and I saw this and started watching it as I was working with clay

I want to see a portable power bank or power station that you could use as a backup battery at home for when the power is out or if you want portable power. station.

I love your vids

Cant wait for the casting

i kinda like clay more pls keep making the vids :D

Make a dry ice bomb (this time with water inside) and put it in a fire and see if it extinguishes!!

Ha nice idea

It could be that there were still some impurities in the clay from the sourcing process you guys did previously. Additionally, I think the initial cracks before the firing were a bad sign that the drying process had left micro and macro fissures in the pieces which were just going to cause further damage upon firing.

Ayyyy its lit

You forgot to score the clay before stacking it on itself, That’s probably why they cracked.

What happens if we boil gallium.

The Prince of Random

I've done pottery on and off for many years, but I've never heard of mixing charcoal ash into your clay body to help prevent cracking. Years ago I did mix various natural fibers into my clay body to make it stronger while it was in the greenware stage because I was making some extreme textures in my sculptures - it worked beautifully, but caused a very smokey bisque firing. Anyway, I'm very curious where you heard about using ash in your clay body - I'd like to check it out. As for your technique of forming your pots, I would strongly suggest you sign up for some type of ceramics class at your local community college. You've got the energy and enthusiasm to go a long way with some quality instruction.

Love from India ❤🍻

When will we see Grants *Big Project?*

You should score the joints between each coil. This increases the contact surface area. Like scratching a surface before you glue it

When doing the technique you showed us, you really want to try getting all of the creases out. I saw that most of the splits were on the coil lines.

wedge the clay... more like beat up

This idea was lit 🔥

On the sides where it broke off, it may have been that you didn't smooth the insides. And besides it would eliminate any cracks where water may leak... i made a coil pot in an art class once and the teacher made sure we either smoothed the inside or outside because of that reason. She said she's had experience with the coils breaking off if it wasnt smoothed out. (Plus it helps with cleaning if its on the inside. Because less cracks and crevices for food or whatever to get in)

Can't wait to do this with my home made forge :)... I just hope that Coal will work...

Next Make a pottery wheel!!!!!!!!!!!!!♥♥♥♥ and then the whole set will be completed !!!! XD

You should make your own pottery glaze and use it with your DIY clay!

The Clay is lit!!!

I have clay class in my high school and i love that class its fun

Where in the world has the king of random been?!

I miss the deadly electronics projects :(

I have not tried this method but I have been successful in using a chimney starter and sitting the clay on top I used hardwood lump charcoal and it made the clay glow orange I kept adding more and moving the clay up i did this for about 4 hours and ended up with sintered clay

Cool pots!

I have started liking the new "Prince of Random"

MAKE A CLAY PAN 😀✌

Love you're vids

what about seeing what the vacuum you guys use to remove the bubbles in the clayu? would love to see that
